VEHICLE-TIRE.

Specification of Letters'Patent.

Patented Dec. 3, 1907.

Application filed February 20. 1907. Serial No. 358.431.

Beit knownthat I, WILLIAM C. TAYLOR, a citizen of theUnited States, residing at Paris, in the Department of the Seine, Republic of France, have invented certain new and useful Im rovements in Vehicle-Tires, of which the follbwing is a specification,

My present invention pertains to improvements in vehicle tires, and has reference more particularly to improved means for preventing the tire from becoming overeated.

The invention is illustrated in the accompanying drawings, wherein:

Flgure l isa perspective view of a portion of a pneumatic tire and the rim of a wheel; Fig. 2 is a side elevation of a wheel, yartly in section; Fig. 3 a transverse sectiona view of the tire and rim; and Fig. 4 a detail view.

The object of the invention is to provide means for bringing air into contact with the tire at that portion which is adjacent tothe rim, whereby the tire will be kept relatively -cool and prevented from exploding or burning owing to the heat generated when the wheel isv traveling at a high rateof speed or when the tire is being run flat in consequence of the puncture of the tube or otherwise.

As an incident of the construction which I employ, the outer casi will be prevented from blowingout shoul the inner tube for an reason explode as, forinstance, if said tu e be defective. In case of such explosion air would pass out through the perforations formed in the supporting platehereinafter referred to in detail, and the tubes which are employed normally to force air into the chamber formed beneath said perforated plate.

As will be readily appreciated by those skilled in the. art, serious difficult obtains with pneumatic tires by reason ofy the fact that when they become over-.heated the rubber or other material of which they are composed deteriorates to such an extent that the outer casing or covering will not withstand the highinternal pressure exerted by the air coniined within the inner tube.

In its broad sense the invention may be said to consist of a foraminous or perforate support for the tire, with means for forcin air into the space beneath said support an thus throu h the openings therein into @om tact' with t etire.

In the drawings I have illustrated a simple form of the invention, wherein A designates the rim of the wheel, shown in this instance erence to Figs. 1 and 3, the plate is provided with a series of openings F, which extend through said late and practically across the entire width t ereof.

By reason of the formation of the rim as shown in the drawingsga recess or chamber G is provided beneath the plate E and the inner `Wall of the rim. Opening into said chamber at 'intervals around the rim are tubes H, preferably formed or bent laterally, as best shown in Figs. 1 and 3, the mouths of some of the tubes opening in one direc-v tion while 'those ofthe other tubes open in the opposite direction. A screen I, will preferably be placed in the mouth of each tube,l to prevent the entrance of dust land other extraneous matter.' If need be, the

tubes may be closedby a cap, as J, Fig. 4,

When the vehicle. is passing through water, mud or the like. Ordinarily the caps will noty be upon the tubes, sothat as the wheel rotates in the direction of the arrow in Fig. 2, the air will be forced into those tubes H the mouths' of which open in the direction of rotation of the Wheel. `As a consequence, the air will be forced out of the intermediate tubes, the mouths of which o en in a direction reverse to the direction ci) rotation of the wheel. These tubes will also serve to suck out the air even though the other tubes do nottend to gather and force the air through the chamber G.

In order to protect the inner tube C fronr injury by comlng into contact with the perforate plate E, a screen K ofne wire or thev be introduced between the plate inner tube burst, .by reason of any defect therein, the air passing therefrom would not blow out through the casing but would pass through the Openings in the supporting plate and out through the tubes.

Having thus described my invention, what I claim is:

1. In combination with a rim; a plate carried thereby, said plate being provided With numerous perforations throughout its length and breadth; a pneumatic tire mounted upon the rim over said perforateplate; and means for admitting air tothe Opposite l side of the plate.

2. In combination with a rim; a perforate late mounted thereon; a chamber formed etween said plate and the a tire mounted'Over said plate; and means for `forcing air into the chamber independentl `of the compression and expansion Of the tire.

3. In combination with a rim having a chamber. extending around the same; a se- `ries of tubes Opening into said chamber; a

plate mounted over the chamber, said plate eing rovided with numerous erfOr-ations throug out its length and brea th, theyperforations being in communication `with the external atmosphere through the .chamber and tubes; and a pneumatic tire carried by the rim and resting upon the plate.

' 4.1m combination with a rim having a chamber extending around the same; a perforate plate carried by the rim and forming chamber formed around the same; a per.

forate plate carried by the rim and forming` the upper wall of the chamber; tubes communicating with said chamber, the mouths of the tubes opening in Opposite directions, whereby upon rotat1on of the wheel' air will be forced into and out .of the chamber; and a tire secured to the rim and bearing upon the plate.

6. In combination `with chamber extending around the' same; a perforate plate carried by the rim and forming the upper wall of the chamber; means for intro ucing air into said chamber; a Wire sceen restin upon the plate; and a tire secured to t e rim and resting 'upon the screen. v

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
